Each of them has been inspected, and both exhibitors and veterinarians say they're doing their part so fairgoers can have fun and be safe.

"I'm going for the big banner again up here," said swine exhibitor Lydia Richardson.

Richardson is an award-winning swine exhibitor. She says it takes hard work and dedication to have a top pig.

"In breeding, they look for real long, big pigs that have a lot of capacity to carry a litter of piglets," said Richardson.

Exhibit swine like Richardson's are coming in hourly at the Kentucky state fair.

There are extra precautions this year after the Centers for Disease Control reported hundreds of swine flu cases at Indiana and Ohio fairs this month.

Incoming swine are required to have a veterinary inspection 72 hours before arrival and are then inspected further on site.

"If anything has an elevated temperature, they pull it off to the side, give them a 30-minute cool down period," said Kentucky State Fair veterinarian Dr. John Moran.

Moran says things are good so far.

"They have not had any swine that have come here that they've sent back home," said Moran.

Exhibitors are also taking precautions, especially with kids who want to pet the pigs.

"We're just, you know, trying to keep them away from mostly their nose. That's where you get it from. Like, if they want to rub them in their back, that'd be fine. If a kid comes up, we're like, you know, 'Be careful. Wash your hands if you do pet them,'" said Richardson.

"It is a concern. A lot of these pigs are going to be resold as breeding gilts to be used on someone's farm, and so any kind of illness is bad for us," said Richardson.

More out-of-state pigs are expected to come in within the next couple of days.
